The chapter considers changes and developments in the content of social work education under the three headings of social science disciplines, understanding human development and relationships, and theories, approaches and methods for practice. At the start of the period under review, social science knowledge (primarily from sociology and social policy) and human development theories predominated, but as their research base and published literature have expanded, theories and methods for practice have become more prominent. The contribution to knowledge from research conducted by social workers themselves is acknowledged, as is the contribution made by experts by experience, both directly and through research interviews. The prominence of sequences on law for social workers is noted. The chapter concludes by asserting that the broad partnership of interests which should determine the content of the social work knowledge base is threatened by Government's much-expanded role, but that most social work programmes continue to ensure a balanced curriculum.
